<a name="index-_002eset-softfloat"></a>

<a name="index-_002eset-hardfloat"></a>
|
|
<p>The directives <code>.set softfloat</code> and <code>.set hardfloat</code> provide
|
|
finer control of disabling and enabling float-point instructions.
|
|
These directives always override the default (that hard-float
|
|
instructions are accepted) or the command-line options
|
|
(‘<samp>-msoft-float</samp>’ and ‘<samp>-mhard-float</samp>’).
|
|
</p>
|
|
<a name="index-Disable-single_002dprecision-floating_002dpoint-operations"></a>
|
|
<a name="index-_002eset-singlefloat"></a>
|
|
<a name="index-_002eset-doublefloat"></a>
|
|
<p>The directives <code>.set singlefloat</code> and <code>.set doublefloat</code>
|
|
provide finer control of disabling and enabling double-precision
|
|
float-point operations. These directives always override the default
|
|
(that double-precision operations are accepted) or the command-line
|
|
options (‘<samp>-msingle-float</samp>’ and ‘<samp>-mdouble-float</samp>’).
|
|
</p>
|
|
<p>Traditional MIPS assemblers do not support these directives.
